    dct:description """Aerial photographs for Pools 2-13 Upper Mississippi River System  were collected in color infrared (CIR) in August of 2010 at 8”/pixel and 16”/pixel respectively using a mapping-grade Applanix DSS 439 digital aerial camera. All CIR aerial photos were orthorectified, mosaicked, compressed, and served via the UMESC Internet site. The CIR aerial photos were interpreted and automated using a 31-class LTRM vegetation classification. The 2010 LCU databases were prepared by or under the supervision of competent and trained professional staff using documented standard operated procedures and are subject to rigorous quality control (QC) assurances (NBS, 1995).
The 2010/2011 land cover/land use spatial data sets for pools 2 - 13 were combined into one data set for this updated product and only wet meadow and wet meadow shrub polygons were retained.  The aerial images underlying these polygons were visually re-interpreted to ascertain if &gt;80% of the polygon was dominated by Phalaris arundinacea (Reed canarygrass). Polygons were then attributed with information categorizing them accordingly.""" ;
